i want to know is there any animation bleed through effect in ipad??????
That iBooks page-curl effect is using a private API (CAFilter). You can't use it in your own app if you target for AppStore.
(The "bleed through" is part of the feature of that private page-curl effect.)

Don't flame me but prior to Oreo I used to put view in a static and keep it switching from fragments and it worked pretty well. In onCreate I simply check if the value of view is not null and in that case I was not inflating. It allowed me to do long task in a fragment in an async and switch to another fragment waiting for the async to complete.
It still works the same way with O except when I rotate the device. In that case I get a blank screen: no layout, no buttons, no text, etc.
I've read https://developer.android.com/about/versions/oreo/android-8.0-changes but didn't find anything.
Do you have an idea to fix this without changing it all?
From the way I understand it. if the Rotation is locked to portrait mode, rotating the device won't force it into landscape mode if portrait mode is locked.
Check out the following post:

Just as annoying as Android Oreo, and unlike most OEM versions of Android I've used. There are new APIs for screen rotation in Android P so it's not clear whether apps need to implement it to be able to lock to landscape from the first go.
Also check out the Android P preview for more info regarding the rotation changes, for some reason it appears to be relevant for the Android Oreo as well.
Feature Overview
Behaviour Overview
so we are developing an app on cross-platform Xamarin. We are now testing it on Android on a few real devices, and we noticed that wherever we have an image with a Tap Gesture Recognizer the tap does not always work.
We tried increasing the section by increasing the image's size and decreasing the used part of the images, but we still have this issue. Its like some times it just doesn't work, even if you did tap on the image.
How can we fix this?
Edit
We updated to the last pre-release of Xamarin.Forms (2.5.0.121934) and it seems to be fixed. We are going to continue running tests to confirm.
Put a hotspot over it or behind it setting image's input to transparent. Hotspot can be whatever works best for you, transparent boxview, contentview etc. It's sometimes better to use hotspots as you can allow users to tap a bit around the image etc.

I was making a user interface using storyboards and when I built my app to see how it would look in the iOS simulator it didn't look like the viewcontroller in the storyboard (some of the buttons were moved around and I had to move one button way down so it was in the place i wanted it to be). Does anyone know why this is?
Yes, the reason is auto layout, it will automatically position elements on a relative basis depending on the device you're running.
You can turn autolayout off, or build for all devices at once and keep it on.

I'm wondering if it's possible for me to embed the quicktime player in a cocoa app. The default QTMovieView is kind of ugly, and the quicktime player window has all the features I need in it, such as full screen, and the maintain aspect ratio button.
I'd like it to operate transparently to the user though. I'd rather avoid making them launch the quicktime app. I'd also like to be able to position the window on the screen. Also, I need to be able to access the current playhead position, and capture when they stop the movie. Any ideas on how I might go about doing this? Or would I have to build out my own custom video player?
A third party component would be fine as well if any exist. I'm just looking for that same quicktime player appearance with the black control bar that appears when hovering over the screen.
Or would I have to build out my own custom video player?
Yes. There is no (reliable) way of getting QuickTime player to integrate into your application.
You should make a subclass of QTMovieView, and maybe use some subviews for the controls.
You can hide the controls if the QTMovieView if you do not like them. In IB switch off Show Controller property.
Alternatively, you can use QTMovieLayer.
Also, it is easy to create your own set of controls that will work directly with the properties and methods of the QTMovie.
Is it possible to write an app to behave like the photo picker does in the Photos app? Namely allowing users to select multiple images and greying out or putting a green tick on the selected ones?
I've tried UIImagePickerController, but that appears to just dim the image when it's touched.
If you’re working with iOS 4 then yes you can (but we’re bound by the oh-so-silly NDA for now), with a custom interface. Else maybe you’d like to look into Three20, it has an image picker which intend to mimic the original and works very well with custom photos (that is, not those in the camera roll or accessible with the Photos app). Maybe you could fork it and add custom behavior.
